[Nhcoll-l] powder coating or zink plated

[Lennart Lennuk]

Shelving will be made from steel. So I might prefer galvanizing.
But is there any chemical influence for collections among those two finishes?

Best!

It depends in part on which metal you’re covering. On steel, zinc plating (Galvanizing) is to some extent self-healing – smaller scratches actually close over, protecting the steel. Powder coating is cheaper, though, and (depending on the powder) very durable; it also looks nicer. On aluminum, of course, only powder coating works; but aluminum actually needs no protective finish.

Hi!

What finish is best for shelving for collections.
There are two choices: zinc plated or powder coating.

The collections are:
geological, entomological, botanical and type based zooloogical collections: (1) mounted animals and skins; (2) bones, horns, eggs, corals, shells; (3) fluid-collection with ethanol and formalin.
